Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed August 6, 1920. Serial No. 401,624.

To (ZZZ whom it may concern:

Be it known that I, PETER C. Ionns, a

citizen of the United States, residing at Chanute, in the county of Neosho and State of Kansas, have invented a certain new and useful Improvement in Railroad-Ties, of which the following is a specification.

My invention relates to improvements in railroad ties. It relates particularly to concrete ties in which the tie is composed of a plurality of concrete sections arranged end to end and adapted for limited vertical movement relatively to each other and held together by suitable connecting means.

The object of my invention is to reduce the wearing away or abrading action of the concrete where the sections abut against each other. A further object of my invention is to provide means for preventing the sections tilting with respect to each other, and to establish a good metallic connection between the sections.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates the preferred embodiment of my invention,

Figure 1 is a top view of my improved tie, showing one rail mounted thereon.

Fig. 2 is a longitudinal sectional view of the same, showing two rails mounted thereon on the line 2-2 of Fig. 1.

' Fig. 3 is a perspective view of the center section, and some of the parts connected therewith.

Fig. 4 is a perspective view of the inner end of one of the end sections.

Fig. 5' is a cross section on the line 55 of Fig. 2.

Fig. 6 is a perspective view of one of the wear plates.

Similar reference characters designate similar parts in the different views.

1 designates two end sections of a concrete tie and 2 an intermediate concrete section.

Extending from end to end in the section 2, is a longitudinal tube 3, through which extends a longitudinal tie bar 1-, which is loosely mounted in the tube 3, and which is also loosely mounted in two longitudinal inwardly flaring tubes 5, mounted respectively in the inner ends of the sections 1.

The tie bar -extends through and preferably supports two wear plates 6, which are interposed between the sections 1 and the section 2. The wear plates 6 bear against the ends respectively of the tube 3 and against the inner ends respectively of the tubes 5.

Two vertical locking pins 7 are mounted respectively in vertical tubes 8 which are provided respectively in the end sections 1. The locking pins 7 extend respectively through two holes 9 provided through the tie bar 4.

By reason of the tie bar e being loosely mounted in the tubes 3 and 5, a limited vertical movement of the concrete sections relatively to each other, is permitted. The wear plates 6 prevent the tubes 5 from out ting into the section 2 and prevent abrading action of the concrete sections against each other, which abrading action in time might permit the sections to tilt relatively to each other. The wear plates 6 further establish with the metal tubes 3 and 5, a metallic connection between the sections.

Rails 10 are respectively mounted on plates. 11 which are embedded in the upper sides respectively of the sections 1. Vertical bolts 12 have their heads engaging the bases of the rails 10 and extend through the plates 11 and have their lower threaded ends provided with nuts 13, which are embedded in the sections 1.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is r 1. In a railroad tie, a plurality of sections disposed end to end adapted for limited vertical movement relatively to each other, means connecting the sections for holding them in operative position, and'against endwise or tilting movement and rigid wear plates interposed between the sections, substantially as set forth.

2. In a railroad tie a plurality of sections disposed end to end and adapted for limited vertical movement relatively to each other a tie bar connecting said sections, rigid wear plates supported by the tie bar and interposed between said sections, and means for locking the tie bar to the end sections, and arranged to hold said sections from endwise movement and from tilting, substantially as set forth.

3. In a railroad tie, a plurality of concrete sections disposed end to end, each section having embedded therein a longitudinal tube, the sections being adapted for limited vertical movement relatively to each other, a longitudinal tie bar mounted loosely in said tubes, means for locking the tie bar to the end sections, and arranged to hold said sections from endwise movement and from tilting and rigid wear plates interposed between the sections, supported by the tie bar and bearing against said tubes, substantially as set forth.

at. In a railroad tie, a plurality of concrete sections disposed end to end and adapted for limited vertical movement relatively to each other, each section having embedded therein a longitudinal tube, a longitudinal tie bar mounted loosely in said tubes, means for locking the tie bar to the end sections, and arranged to hold said sections from endwise movement and from tilting and rigid wear plates interposed between the sections and bearing against said tubes, substantially as set forth. 7 7

In testimony whereof I have signed my name to this specification.

PETER C. ICKES.
